Abstract

The utility model relates to a sand settling device for water supply pipes, which is characterized in that the utility model is mainly composed of a water supply pipe (7), a sand settling pipe (3), a water accumulating pipe (1) and a sand discharging pipe (4), wherein the sand settling pipe, the water accumulating pipe and the sand discharging pipe are arranged in the water supply pipe, the sand settling pipe is arranged in the middle of the water supply pipe, the sand discharging pipe is arranged on the bottom of the sand settling pipe and the water accumulating pipe is arranged at a port of the water supply pipe above the sand settling pipe. Due to the artful design, the sand settling device for water supply pipes of the utility model has the advantages of simple structure and favorable sand removing effect. A hydropower station has an actual condition that the higher a water head is, the larger the harm of sands entering a motor is. After the sand settling pipe is lengthened, the utility model also has the advantage that the higher the water head is, the more obvious the effect of sand settlement is.

Description

A kind of flow pipe sand setting device

The utility model relates to the flow pipe sand setting device of using in a kind of power station.

The flow pipe of power station use at present is generally straight tube, in the big section of silt content, though through repeatedly sand setting, desanding processing, still have silt particle to enter flow pipe, thereby enter the water wheels unit, the water wheels turbines vane is caused wearing and tearing.

The purpose of this utility model provides a kind of simple in structure, and desanding effect is good, prevents the frayed power station of water wheels turbines vane flow pipe sand setting device.

The utility model is achieved in that flow pipe sand setting device mainly is made up of flow pipe and sand sediment pipe, polywater pipe, the sediment outflow pipe be located in it, sand sediment pipe places in the middle of the flow pipe, the sediment outflow pipe is located at the sand sediment pipe bottom, and the polywater pipe is located at the flow pipe mouth place on the sand sediment pipe.

Be provided with sand block plate ring in the sand sediment pipe, sand sediment pipe is by the supporting rib supporting that connects with flow pipe.Sediment outflow Guan Yiduan is provided with valve.

Flow pipe sand setting device of the present utility model is owing to be skillfully constructed, and it is simple in structure that it is had, and removes effective advantage.The actual conditions in power station are, head is high more, and the sand evil that enters motor is big more, as long as the lengthening sand sediment pipe, it is high more that this device also has a head, the significant more advantage of sand setting effect.

Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A-A sectional drawing of the present utility model.

Among the figure, 1-polywater pipe, 2-desilting piping support muscle, 3-desilting pipe, 4-arranges sand tube, 5-valve, the husky ring of 6-retaining, 7-flow pipe, 8-polywater piping support muscle.

As shown in the figure, the utility model mainly is made up of flow pipe 7 and sand sediment pipe 3, polywater pipe 1, the sediment outflow pipe 4 be located in it.Sand sediment pipe places in the middle of the flow pipe, and by supporting rib 2 supportings that connect with flow pipe.The quantity of supporting rib is determined by actual needs.The sediment outflow pipe is located at the sand sediment pipe bottom, and the polywater pipe is located at the flow pipe mouth place on the desilting pipe, and supporting rib 8 supportings are arranged, and the quantity of supporting rib is determined by actual needs.Be provided with sand stop ring 6 in the sand sediment pipe.Sediment outflow Guan Yiduan is provided with valve 5.

During work, water enters sand sediment pipe by the polywater pipe, and sand is sunken to the sand sediment pipe bottom because of action of gravity, and clear water then overflows from the sand sediment pipe top and enters flow pipe, and sand can be discharged from the sediment outflow pipe.The sediment outflow pipe wet season can be grown out, and then open and close according to circumstances dry season.

Claims

1, a kind of flow pipe sand setting device, it is characterized in that mainly forming by flow pipe (7) and sand sediment pipe (3), polywater pipe (1), sediment outflow pipe (4) of being located in it, sand sediment pipe places in the middle of the flow pipe, and row's sand tube is located at the sand sediment pipe bottom, and the polywater pipe is located at the flow pipe mouth place on the sand sediment pipe.

2, by the described sand setting device of claim 1, it is characterized in that being provided with in the sand sediment pipe the husky ring of retaining (6), sand sediment pipe is supported by the supporting rib that connects with flow pipe (2).
